Features

• Added initiatorOrigin to webRequest and protocol handler requests, DownloadItem.getInitiatorOrigin(), and a trailing frame argument to the will-download and preconnect session events. #53703 ^{(Also in 43, 45)}

Fixes

• Added validation to protocol.registerSchemesAsPrivileged() to reject protocol names that do not conform to RFC 3986 URI scheme grammar. #53743 ^{(Also in 45)}

• Fixed a crash when a webContents navigated to the Chrome Web Store and the page invoked the unsupported chrome.webstorePrivate API. #53776 ^{(Also in 45)}

• Fixed a main-process crash when an app called loadURL() again right after a load failed because the renderer process exited before the page committed. #53943 ^{(Also in 43, 45)}

• Fixed a memory leak on Windows when app.getPreferredSystemLanguages() was called. #53868 ^{(Also in 43, 45)}

• Fixed a potential UAF in app.getPreferredSystemLanguages() on Windows. #53865 ^{(Also in 43, 45)}

• Fixed a renderer crash that could occur when printing from an iframe. #53762 ^{(Also in 43, 45)}

• Fixed a renderer crash when an iframe was removed right after loading with nodeIntegrationInSubFrames enabled and sandbox disabled, e.g. on pages that embed Meta Pixel. #53885 ^{(Also in 42, 43, 45)}

• Fixed a Windows renderer crash when no default locale could be determined. #53947

• Fixed helper executables on macOS starting a second app instance when launched without a process type, for example through child_process.fork() with the runAsNode fuse disabled; fork() now throws in that configuration. #53840 ^{(Also in 45)}

• Fixed V8 code caching for https scripts loaded by file:// and custom-scheme pages. #53745 ^{(Also in 45)}

• Fixed webContents emitting unresponsive right after the system wakes from sleep on Windows, and emitting responsive when a hung window was hidden rather than when it recovered. #53764 ^{(Also in 45)}

• Fixed webContents.capturePage() on offscreen windows returning an image resampled to the display's scale factor instead of rendered at the window's offscreen.deviceScaleFactor. #53816 ^{(Also in 43, 45)}

• Fixed Window Controls Overlay CSS environment variables and navigator.windowControlsOverlay not being populated for WebContentsViews in a BaseWindow. #53812 ^{(Also in 45)}
